HUB-ATTACHER.

To all whom t may concern: f d

Be it known that I, THOMAS HAUn'roN, a citizen of the United States, residing 4at Belle Vernon, in the county ofFayette and State of Pennsylvania, havey invented certain new and useful Improvements in Hub- Attachers; and I do declare the following to,

be a full, clear, andk exact description of the invent-ion, such as will enable others skilled in the art to which it appertains to make Vand use the same. y f

This invention relates to the class of carriages and wagons,'and more especially to hub attaching devices; and the objects of the same are to produce improved means whereby the hub may be attached to or detached from the spindle ofthe axle at will and without the uselof tools, and improved means forl oiling the interior of said hub automatically. These and other objects are the manner hereinafter more fullydescribed andclaimed, and as shown inthe drawings,

. whereinl Figure 1 isA a*y vert-ical section through a hub andthis attacher with its parts complete, and Fig. 2 is across section on the line 2 2 of Fig. 1. Fig.v 3 isa horizontal section through thehub and attacher, taken on about the line 8-3 of Fig.r1; Fig. A is a vertical section of a slight modification, and Fig. 5 is a horizontal section on the line 5;-5 of Fig-.4.

* In the drawings the letter A designates thefa'xle or it may be the spindle only of the f n the outer end ofthe reservoir or bore 1 inthe axle, the tip of the finger holding said.v pin 8 yelevated until itis passed into said bore and is held elevated by the lower wall thereof. The plug is then ypushed Ainward luntil the hole 6 and lgravitypin 8A stand axle, andordinarily this member does not rotate although rin some cases it may rotate and yetbe used in connection with my in-Q vention; .andA the letter I-I in the present instance designates awheelor roller, yor itmay l be-the hubof `such la wheel or roller whose interior it is desired tolubricatearound the axle or spindle therein. Also it is the purposeof the presentjinvention to provide im* proved means for mounting the membery I-I 1 removably on thefmember kA without employing the usual nut screwed upon orycotter pinv passed throughthe outer extremity4 of the spindle, anfilv Without. the necessity for ,5o

any member which shall project beyond the outer end ofthe wheel or hub to strike against passingfobjects or tofbe struck by them.

Comingnow more particularlyto the details of the present invention, the axle A is bored in its end with apreferably cylindri-k v I Patented Dec. 17, 1912., .Application fuedvaugust 16, 1912. serial No. 715,422.

eal and internallysmooth cavity *formingani i oil reservoir 1, andthe lowerside of the axle f `'is cross-bored with an outlet hole 2 communicating with the cavityk or reservoir lnear i the-inner end ofthe latter. During the ro-V tation around the axle spindle of the hub (or 4;the bushing within the same if it have a bushing) it is obvious 4that yoilflowing out the hole 2 willbe immediately applied to the i point where friction would otherwise occur, y but as this hole is surrounded by the hub no dirt kcan get into it and what sediment ex-` ists in the oil will settle to the bottom.

' Fork @awning uw hub to the spindle I make use of a plug y3 having a large flat head plug at one. side is continuedk or'.y projected into ya tongue 5 pierced Awith, a hole 6 adapt-V -fed to lregister with another hole `7 in the lower wall of the reservoir, but this hole 7 is `1 no-t the same as the hole' 2 landisfby prefer- Y ence drilled at a point nearer the extremity of the axle than said outlet hole Qfforthe oil. A gravity pin Shaving a rslightly enlarged head 9 at itsfinner' end is seated in the holesl 6 and 7, which .aline when the 'l washer or head 41 at the outer end of the plug stands againstl the extremity of the spindle and holds the wheely H lin place, and at this y time the plug' closes, the outer kend ofl the resl ervoir 1 as will be'clear'. y .y ,To yconnect the parts, the tip 0f the gravity pin lis passed into 'the inner end of the holet,`

and the inner endoftheplug Spassed kinto over the hole 7 through the lower wall of the,

reservoir, when. the pin-,falls by gravity and lthe parts arev connected as shown in Fig. 1 1ofthe drawings, To disconnect the parts the vehiclecarrying the axle A must be inf `verted-, `and this` permits the pin 8y by its weightfto fall.intofthereservoir 1 so that its tip elearsthe holey 7 and possibly also falls outy of the hole 6 after which thel entire plug i intended to stand against the outer end of. the hub as shown, and the inner end ofthe i esr eanbe withdrawn, and then Vthe wheel H re moved In the act of cleaning out thel reserf Voir1 thepn Willbe foundtherfen I have suggested above that it; might 'be -that the axle revolves. v.For instance, this device might be applied to thek Supporting shaft of an elevator bucket, which shaft stands one side up as the bucket ascends and is inverted as the bucket descends; and in the event thereof the pin might drop out of place. Accordingly, means must then be provided to sustain the pin even when the shaft rotates or is inverted occasionally, and ya detail of construction eEect-ing this purpose is illustrated in Fig. 5 of the drawings. This consists of a spring made of light steel wire as will be described below, although the particular formation and attachment of this spring will depend upon other details of construction as will be seen from what follows. The broad idea is, however, that the light spring is to hold the gravity pin to its place with force sufficient to prevent its tip from slipping out of the hole 7 when the axle is inverted or when it revolves, unless the entire wheel and hub be thumped or pounded with sufficient force to jiggle the pin inward against the force of this spring.

Any suitable means may be provided for lling the reservoir 1 with oil, but in order that the attaching device shall not necessarily have to be withdrawn for the purpose of filling the reservoir, I may make use of the following details of construction: The plug 3 as shown in the drawings is a tubular plug, its bore 10 opening through the washer or head 4 in a reduced filling orifice 11 normally closed by a ball 12 pressed to its seat by a coiled spring 13 standing within said bore with its other end against a cross pin 14. When the plug is thus made, what would normally be its lower side is continued into the tongue 5 above described, which tongue is pierced with a radial hole 6 for the passage of the gravity pin 8, and the latter moves across the inner end of the plug when the axle is inverted as described. In order to ill the oil reservoir it is only necessary to insert the tip of an oil can or a filling can into the orifice 11 and press the ball 12 away from the same, then inject the oil which flows into the oil reservoir 1, and remove the tip of the can. The seating of the ball against the inner side of the orifice 11 normally closes the reservoir so that dust and dirt may not get into the same nor oil escape excepting through the outlet hole 2 as is desired. I wish it understood, however, that this is only one of many expedients which may be resorted to for the purpose of filling the reservoir with oil, but I consider it particularly serviceable in this connection, and simple and inexpensive.

A slight modification or amplification of this invention is illustrated in Fig. 4 and referred to above, and this when used in connection with the cross pin 14 and gravity pin 8 is a piece of spring wire bent into a flat coil 2O at its center to rest on the head 9 of said gravity pin 8, thence into parallel arms 21, and the two arms into alined coils 22 loosely embracing the pin 14, and the ends of the spring thence continued in straight lines as at 23 adapted to rest inside the bore of the plug or within the bore of the reservoir and hold the entire spring in a normally horizontal plane. Then this attachment is applied to the device above described, the pin 8 is held in place not only by its gravity but also by the downward pressure of the flat coil 20 upon its head, and therefore, the material of which this spring is composed should be so light that when the axle is inverted it is possible to unseat the wheel. I do not wish to be limited to the details of construction further than as necessary to carry out the spirit of this invention. Also I wish it to be understood that the hub attaching device may be employed without necessarily using all the details of the lubricator, or the reverse; but I prefer to employ both features of this invention because they coact to produce a desirable and successful whole.
